Compare the fate of pyruvate in alcohol fermentation and in lactic acid fermentation
Answer:
Fate of pyruvate in alcohol fermentation:
Alcoholic fermentation may be defined as a type of metabolic pathway in which occurs generally in the yeast and microorganism. This process occurs in the absence of oxygen. The end products are ethanol, carbon dioxide and ATP from the pyruvate molecule.
Fate of pyruvate in lactic acid fermentation:
Lactic acid fermentation may be defined as the metabolic pathway that generally occurs in the muscle cells. This process occurs in the limited supply of oxygen. The end products are lactic acids and ATP from the pyruvate molecule.

The solute most abundant in phloem sap is _____. see concept 36.5 (page 797) the solute most abundant in phloem sap is _____. see concept 36.5 (page 797) amino acids minerals sugar hormones water
The most abundant solute in phloem sap is sugar, specifically sucrose. This sucrose is transported from source cells into companion cells and then into sieve-tube elements, creating a flow from source to sink.
Explanation:The solute most abundant in phloem sap is sugar, specifically sucrose. Phloem sap is an aqueous solution that contains up to 30 percent sugar, alongside minerals, amino acids, and plant growth regulators. Sucrose is actively transported from source cells into companion cells and then into the sieve-tube elements. This reduces the water potential, which causes water to enter the phloem from the xylem, thereby increasing pressure and causing the bulk flow of phloem from source to sink. Unloading at the sink end of the phloem tube occurs by either diffusion or active transport of sucrose molecules from an area of high concentration to one of low concentration.

Fossil fuels are formed by the decomposition of dead plants and animals which flow chart describes the correct energy transformation when a car burns fossil fuels to accelerate
Final answer:
Fossil fuels are sources of stored solar energy that, when burned in a car engine, undergo a transformation from chemical energy to thermal, then mechanical, and finally kinetic energy, in accordance with the law of conservation of energy.
Explanation:
Fossil fuels, such as coal, oil, and natural gas, are energy sources with a high hydrocarbon content that have formed in the Earth's crust from the anaerobic decomposition of dead plants and animals over millions of years. The transformation process involved in the formation of these fuels includes the conversion of the energy from sunlight into vegetation, followed by chemical changes due to high pressures and temperatures over geological times without oxygen.
When a car burns fossil fuels to accelerate, the correct energy transformation flow chart would show the following sequence: chemical energy from the fuel is first transformed into thermal energy due to combustion. Then, this thermal energy is converted into mechanical energy by the engine, which ultimately leads to kinetic energy as the car accelerates.
According to the law of conservation of energy, energy is never lost but merely changed from one form to another. This is evident in the process of fossil fuel combustion in car engines, where the ancient solar energy stored in these fuels is released and transformed to power the vehicle.
The nurse is caring for a client with nursing diagnosis of ineffective tissue perfusion. which area of the heart would the nurse anticipate being compromised?
Final answer:
In cases of ineffective tissue perfusion related to the heart, the myocardium is most likely to be compromised due to conditions such as heart failure or ischemia caused by narrowed or blocked coronary arteries. This can result in inadequate oxygenation, cell death, and severe impairment of heart function.
Explanation:
When a nurse is caring for a client with an ineffective tissue perfusion nursing diagnosis, it implies that a certain area of the heart is not receiving an adequate blood supply, which could be due to heart failure or ischemia. The heart muscle that is most likely to be compromised is the myocardium, particularly the regions supplied by the narrowed or blocked coronary arteries.
Heart failure occurs when the heart can't pump with sufficient force to meet the body's needs, leading to inadequate oxygenation of tissues, which can result in cell death and severe impairment of heart function. Cardiac muscle, composed of cells with endoplasmic reticula, requires proper functioning to manage calcium ions and ensure adequate contractile force; thus, any impairment in this system can lead to heart failure.
Furthermore, the heart's ability to appropriately allocate resources and oxygenated blood during various states of activity is essential for maintaining cardiovascular homeostasis. When an immunocompromised individual, such as a patient with chronic myelogenous leukemia, experiences additional stress or illness, this can exacerbate heart function and lead to further complications due to the limited regenerative capacity of the cardiac muscle tissue. Ultimately, untreated heart failure can lead to the failure of other organs and severe systemic effects.

Which of the following statements characterizes an excitatory neuron?
It sends an impulse back to the cell body of a neuron.
It helps carry an impulse to the next neuron.
It stops the passage of an impulse at a neuron.
It sends an impulse back to the cell body of a neuron
Final answer:
An excitatory neuron facilitates the transfer of an impulse to the next neuron by releasing neurotransmitters at synapses, which then activate the subsequent neuron, enabling transmission of the neural signal.
Explanation:
Characteristics of an excitatory neuron include its ability to facilitate the movement of an impulse to the next neuron. This is achieved by the release of neurotransmitters at the synapse, which carry the nerve impulse from one neuron to another. Within a neuron, the dendrites receive incoming signals and transfer the impulse to the soma (cell body). The axon hillock then integrates these signals and if the threshold of excitation is met, an action potential is generated. The axon carries this action potential away from the cell body towards other cells, ultimately reaching specialized endings called axon terminals where neurotransmitters are released. These neurotransmitters then bind to receptors on the dendrites of the next neuron, opening ion channels, allowing for the continuation of the impulse.
In pea plants, yellow seeds (y) are dominant and green seeds (y) are recessive. a pea plant with yellow seeds is crossed with a pea plant with green seeds. the resulting offspring have about equal numbers of yellow and green seeded plants. what are the genotypes of the parents?
The parental genotypes for the pea plants are Yy for the yellow-seeded parent and yy for the green-seeded parent, which explains the equal numbers of yellow and green seeded offspring.
Explanation:Understanding Parental Genotypes in Pea Plants
In pea plants, yellow seeds are dominant (Y) and green seeds are recessive (y). Given that a cross between a pea plant with yellow seeds and one with green seeds yields offspring with about an equal number of yellow and green seeds, we can deduce the genotypes of the parents. The parent with yellow seeds must be heterozygous (Yy) because they contribute both the dominant and recessive alleles. The green-seeded parent is homozygous recessive (yy) because green is the recessive trait and can only be expressed phenotypically when two recessive alleles are present.
To predict the genotypes and phenotypes of the offspring, a Punnett square analysis can be employed. In this scenario, the Punnett square would show 50% of the offspring having yellow seeds (Yy) and 50% with green seeds (yy), supporting the observation of equal numbers of yellow and green seeded plants among the offspring.

In pea plants, yellow seeds (y) are dominant to green seeds (y) and round seeds (r) are dominant to wrinkled seeds (r). the genes for seed color and seed shape are on different chromosomes. two true-breeding parents, one with yellow round peas and the other with green wrinkled peas, are crossed. what are the genotypes of the parents, and what kind of gametes will they produce?
Final answer:
The true-breeding parents of yellow round peas and green wrinkled peas have genotypes RRYY and rryy, respectively. They will produce RY and ry gametes and all F1 offspring will display the yellow round seed phenotype with a genotype of RrYy.
Explanation:
In pea plants, the genotype for yellow round seeds is RRYY, where 'R' represents the dominant round trait and 'Y' represents the dominant yellow color. The green wrinkled seeds have the genotype rryy, where 'r' is the recessive wrinkled trait and 'y' is the recessive green color. When these two plants are crossed, the genotypes of the parents would be RRYY (yellow round) and rryy (green wrinkled). Because these are true-breeding plants, they are homozygous for their respective traits.
The gametes produced by each parent will reflect one allele for each trait. The round yellow parent (RRYY) will produce gametes with the RY allele, and the green wrinkled parent (rryy) will produce gametes with the ry allele. When these gametes combine during fertilization, all the F1 offspring will have the genotype RrYy, which are dihybrids, displaying the dominant phenotype of yellow round seeds.

Crenation (shrinking) is likely to occur in blood cells immersed in ________.
a.a hypotonic solution
b.blood plasma
c.a hypertonic solution
Crenation (shrinking) is likely to occur in blood cells immersed in C) a hypertonic solution.
In a hypertonic solution, the concentration of solutes outside the blood cells is higher than inside the cells. As a result, water molecules tend to move out of the cells through osmosis, leading to a loss of water and the subsequent shrinkage of the cells.
This can occur when blood cells are exposed to a solution with a higher salt concentration or other solutes. Conversely, in a hypotonic solution where the concentration of solutes outside the cells is lower, water molecules will move into the cells, causing them to swell and potentially burst. In blood plasma, which is isotonic to blood cells, there is no net movement of water, and the cells maintain their normal shape and size.
Therefore, the correct answer is C) a hypertonic solution.
